Abstract
A distal rate control device, which can be conveniently interposed between a fluid supply line and fluid delivery line for precisely controlling the rate of fluid flow toward the delivery line. The device includes a readily adjustable flow rate control device having a novel flow control plate that can be placed in fluid communication with the fluid supply line and with the fluid delivery line. The flow control plate is provided with a plurality of elongated fluidic flow control channels that are in communication with a rate selector member that is rotatably carried by the device housing. Rotation of the rate selector member places a selected one of the flow control channels in communication with the fluid delivery line.
